It should be noted that the amount 151?sition by suitable set screws 34. This stop of ybacklash orloosenessinthe .pivotal .con-v le@ nections for the link 62, the intermeshingengagement of the teeth of the bevel gears 52, and the engagement of thepins 46 in the slots 56, is all immaterial and may be very large withoutinterfering with perfect operation of the device. It is only necessaryto adjust the link 62 to produce enough motion to take up this backlashor 1looseness and still provide a sufliciently long stroke for thejoggers, to produce a perfect result in the formation of the pile. rEheextreme limit of inward movement of each jogger 38 may be determinedaccurately since this limit 4is reached when the backlash is all takenup in one direction, and the set screws 44 make precise adjustment afairly easy matter.

It should also be noted that the bevel gears 52 only rotate through arelatively small fraction of a rotation. When the teeth in engagementbecome worn, it is a simple matter to loosen the gears on their shaftsand rotate them 150 or so to bring fresh teeth into engagement. A verylong life for these parts, even when cheap stock gears are used, is thusassured.

The pile 72 formed by the joggers may rest in the first instance on astarting board 74 which, in turn, rests on the top table 76 of a wheeleddelivery truck made up of said table and of four wheels 7 8 mounted onthe bottom thereof, all of which may be caster wheels if desired. 'Iomaintain the top of the pile at a substantially constant level duringits formation, it is necessary to lower the table 76 at a slow rate tocompensate for the increase in the height of the pile. I haveillustrated clips 80 in the form of angle-irons underlying the sideedges of the table 76. From each end of each clip a sprocket chain 82runs up and over a sprocket 84 and down again to a counterweight 86. Allfour sprockets are connected together to raise or lower the corners orthe table in unison, as by mounting the sprockets on each side onlongitudinal shafts 88 and interconnecting the shafts by a transverseshaft 90 across the front of the frame, and bevel gears 92 at the frontcorners.

The connections for'lowering the table at a speed equal to the growth inheight of the pile, comprise an actuating link 94 connected to anysuitable oscillating part of the press. I have illustrated this link asconnected at 96 to the pivot interconnecting the lever 98 with a link100 employed to actuate one of the rolls 102 of the press itself. Thislever is rocked by a cam 104 engaging a roller 106 at the lower end ofthe lever, the lever being normally held against the cam by acompression spring 108 abutting a bell crank arm 110 projectingrearwardly from the lever.

The front end of the link 94 actuates a crank 112. Referring moreparticularly to Figs. 4 and 5, the right-hand shaft 88 extends through aworm-wheel 114; through a splined clutch 116 for connecting the wormwheel to the shaft; and terminates in a handwheel 118 provided with acrank handle 120. Below the worm-wheel I support a wormshaft 122 insuitable bearings. The wormshaft carries the worm 124 meshing with theworm-wheel 114; an actuating ratchet 126; and the crank arm 112, thecrank arm being free to rotate on the shaft. The crank arm extends bothabove and below the shaft and at its upper endvcarries a suitable pawl128 pivoted at 130 and normally urged by a spring 132 into a position ofengagement with the teeth of the ratchet 126. rEhe wormywheel 114 isenclosed in a suitable housing 134, and on the face of this housing Imount a shield comprising a vertical plate 136 with a horizontal shelf138 overlying the teeth of the ratchet 126. The mounting is by means ofan arcuate slot 140 in the plate 136 and a fastening screw 142. Bymoving the shield to various positions around the axis ofthe shaft 122as a center, part or all of the active stroke of the pawl 128 may berendered ineffective for rotating the ratchet 126 by holding the pawlout of contact with the ratchet. It is only the last portion of thestroke after the pawl has moved beyond the edge of the shield 138 thatwill be effective. In this way, a fairly large number of slightlydifferent speeds of lowering may readily be obtained.

I prefer to extend the shaft 122 through the crank 112, and to mount ahand-wheel 144 with a crank handle 146 on the end thereof.

Then the pile is to be delivered, either because it has grown to thecapacity of the receiving means, or because the requisite number ofsheets for the particular job in hand have been printed, the table 76 islowered until the wheels 7 8 come to rest on the angle braces 16. slightfurther movement of the clips 80 will leave them dangling freely justbelow the edges of the table. The front legs of the front uprights 12are notched as at 148 to clear the edges of the table and permit thetable and pile to roll out of the frame. To make this movement lessabrupt, the braces 16 are extended beyond the front uprights 12 andtheir horizontal legs are separated from their vertical legs by sawing aslot, after which the horizontal legs are bent downward as at 150 toform an inclined track section for easing the wheels of the truck downto the level of the floor supporting the frame.

After the finished pile has been thus removed, an empty truck can beslipped back into the frame. By moving the clutch 116 to the left fromthe position shown in Fig. 2,

the crank handle can be operated to raise the table quickly toapproximately the level desired fer beginning a new pile. Then, theclutch may be moved to connect the wormwheel to the shaft, and the crankhandle 146 lli rimaste may be operated to bring the table to the preciselevel desired. As soon as the Inachine is put in operation, the plate136 may be shifted to the position necessary for automatic lowering ofthe table at the speed appropriate for the thickness of paper beingfrdelivered by the press.

Thetype of press'illustrated, When it is not used in conjunction with myimproved pile receiving means, lcarries a simple table mounted on asupport at 152 upon Which the papers passing up the conveyor 154 mayfall and accumulate in an irregular pile. The edges of the sheets inthispile may then be adjusted by hand by standing the pile on edge. When myimproved device is to be associated with such a press,` it is impossibleto position the table 76 close enoughv to the conveyor 15-1 to receivesheets therefrom because the support 152 is in the Way.

l have provided a detachable auxiliary conveyor'comprising a trame 156provided with conveying belts 158 of any suitable or desiredconstruction. T his trame is provided with adjustable struts 160 adaptedto rest on ,the front end or the support 152, and its sides entendbeyond the end of the conveyor belts 158 and are notched as at 162 totake over the stationary shaft 164 carrying the end roller of theconveyor 154. This vend roller may be provided with a pinion l66, and apower connection to the conveyor belts 158 may be established through anidler 168 driving a pinion 170 on'the adjacent end roll tor the belts15S. The idler 168 and the end roll carrying the pinion 170 arejournaled in the frame 156. lt will be obvious that this irame may beset in place on a moments notice and removed again to permit the pressto operate with its ordinary table Whenever the nature ot the Work isnot such as to require the use ot my pile-forming and delivery means.The edge or' the sheet leaving the conveyor belts 156 may be guided downagainst the stop 28 by strip of light sheet metal 172.

TWithout further elaboration, the foregoing Ywill so tully explain myinventionV that others may, by applying current knowledge, readily adaptthe same 'tor use under various conditions ot service. It will also beobvious 'that all the features described need not necessarily beemployed in conjunction, as they may advantageously be utilized invarious combinations and subcombinations.`
